About this product
Unlike universal window adapters, this adapter is specifically designed to fit selected VELUX roof windows. The profile is shaped to match the lower window sash, creating a secure and stable connection for your portable air conditioner exhaust hose.
🆕 New Version (Released July 6, 2026)
On July 6, 2026, a new version of this adapter was introduced with an improved internal design that allows significantly better airflow, helping your portable air conditioner operate more efficiently.
At the same time, the matching VELUX filler panel was also redesigned to be fully compatible with the new adapter.
If you specifically prefer the previous adapter version, please send me a message before ordering and I will do my best to accommodate your request.
For an even better seal, you can also purchase a matching filler panel from my shop that closes the remaining open section of the window. This helps reduce warm air entering the room and improves the overall efficiency of your air conditioning system.
Find the matching product in the AC adapter category in our store.
Don't have a VELUX window? No problem! I also offer several universal AC window adapters in my shop that can be customized to fit many other roof window types and dimensions.
Why Choose This Adapter?
✅ Designed specifically for compatible VELUX roof windows ✅ Fits directly onto the lower window profile ✅ Secured by the VELUX ventilation lock position ✅ Improved cooling efficiency and reduced warm air leakage ✅ Matching filler panel available separately ✅ Durable PETG construction
Compatibility
Designed for compatible VELUX roof windows including many:

Please verify your window model and dimensions before ordering.
📏 Choosing the Correct Size
When placing your order, please select the size based on the outside diameter of the adapter outlet where the air conditioner hose attaches.
The selected size should match the inside diameter of your AC exhaust hose.
Please refer to the product images, where the measurement location is clearly shown.
If you are unsure which size you need, feel free to contact me before purchasing.
